East Harbor

East Harbor is the name of a tidal estuary in Truro, Massachusetts that was formerly a harbor until it was cut off from Cape Cod Bay. It is now within Cape Cod National Seashore.

Comparison of two official maps of Provincetown, one dated 1835, and the other, 1889.

The East Harbor isolated Provincetown from other towns (top), until the railroad arrived in 1873^[1]^[2]

After an oxygen depletion and fish kill in 2001, the town and the National Park Service began to explore options to restore the estuary. Over time, the blockage of tides has caused numerous ecological problems. The lack of tidal flushing had deprived the system of salty, nutrient-poor, oxygen-rich Cape Cod Bay water and it became a stagnant freshwater pond. These conditions resulted in midge outbreaks, fish kills, and a proliferation of exotic species. In 2002, the National Park Service received permission to open up the tidal locks between the two bodies of water to improve the quality of water in the harbor.

In June 2008, it was renamed back to its original name from Pilgrim Lake, a name which it held for over one hundred years.^[4]

The 720-acre East Harbor system, includes Moon Meadow, Salt Meadow and the East Harbor lagoon. From Route 6, while driving along the edge of the lagoon, one can see stunning white dunes on the far side.
